On determining efficient finite mixture models with compact and essential components for clustering data

Ahmed R. Abas
2013 Egyptian Informatics Journal  
In this paper, an algorithm is proposed to learn and evaluate different finite mixture models (FMMs) for data clustering using a new proposed criterion.  ...  Essential components have minimum mutual information, that is, redundancy, among them, and therefore, they have minimum overlapping among them.  ...  However, due to the dependency on the EM algorithm, the model selected using these criteria is not necessarily the best model for clustering small data sets.  ...

Summarizing Finite Mixture Model with Overlapping Quantification

Shunki Kyoya, Kenji Yamanishi
2021 Entropy  
Finite mixture models are widely used for modeling and clustering data. When they are used for clustering, they are often interpreted by regarding each component as one cluster.  ...  The primary purpose of this paper is to establish a theoretical framework for interpreting the overlapping mixture models by estimating how they overlap, using measures of information such as entropy and  ...  Analysis of Artificial Dataset To reveal the differences among the criteria, we conducted experiments with artificially generated Gaussian mixture models.  ...

Enhancing the selection of a model-based clustering with external categorical variables

Jean-Patrick Baudry, Margarida Cardoso, Gilles Celeux, Maria José Amorim, Ana Sousa Ferreira
2014 Advances in Data Analysis and Classification  
In cluster analysis, it can be useful to interpret the partition built from the data in the light of external categorical variables which were not directly involved to cluster the data.  ...  It is noteworthy that each mixture model is fitted by the maximum likelihood methodology to the data, excluding the external variables which are used to select a relevant mixture model only.  ...  Whereas cluster analysis is an exploratory data analysis tool, any available information on the objects to be clustered, available in addition to the clustering variables, could be very useful to get a  ...
